Hartzell Propeller has received a Supplemental Type Certificate (STC) to replace McCauley propellers on Mooney M20M/TLS/Bravo series single-engine aircraft with their 75-inch diameter three-bladed aluminum props. Airplanes powered by TIO-540-AF1A and TIO-540-AF1B Turbocharged Lycoming Sabre engines are covered by the STC.
“Installing Hartzell’s Scimitar-style prop covered by this STC delivers 8-10 percent improvement in climb performance, a 2-3 knot increase in cruise, and looks terrific on the ramp coupled with Mooney’s signature tail,” said Hartzell President JJ Frigge. “And it has the Hartzell Top Prop 2,400 hour, 6 -year time between overhaul, and warranty until first overhaul,” he added.
The Hartzell Propeller Top Prop kit, HC-I3YF-1RF/F7498-1, is available for $15,839 and includes a propeller, all-composite spinner assembly and STC documentation. Additionally, a TKS ice protection kit is available at an additional charge, while electric de-ice approval is pending.
